4 Claims.

Business forms are in common use which em:

body sheets, usually with identical or comple-.

mentary printing thereon and either with or without permanentlyassociated carbon sheets between them, in which the sheets are fastenedtogether along an edge forming a book-like pad. Such fastening iseffected by adhesive, wire stitching or other means. Wire stitching hasobvious disadvantages, and especially when the number of sheetsincreases, securing them together by means of adhesive has hithertoentailed the multiplication of expensive mechanisms in manufacture andobjectionable bulkiness at the joint. My invention provides for theproduction of a multiplex form or pad obviating such criticisms.

My invention may be well understood by reference to the followingdescription taken in connection with the accompanying drawing, where-1n:--

Fig. 1 is a plan of a pad with parts successively broken away;

Fig. 2 is a section on the line 2-2 of Fig. 1 on an enlarged scale; and

Fig. 3 is a plan showing the successive elements of the pad relativelydisplaced.

As an example of my invention I will herein illustrate and describe apad or form consisting of five parts and have indicated all these partsas printed sheets. It will be understood, however, that the sheets maydiffer in quality, color, legends printed thereon and even in size.

Referring now to the drawing, the pad there shown comprises three pages5, 7 and 9 and a back member or sheet 11, herein a similar page, towhich 35 the pages 5, '7 and. 9 are held beneath a front sheet 13, againin the example shown a page similar to the pages 5, l and 9 and of likearea, and

a separate piece from the rear sheet 11 although this is not necessary.Pages 5, 7 and 9 may be 40 provided along an edge thereof with openings15,

preferably circular openings which, besides providing for the securingtogether of the various parts in pad form as hereinafter described, mayserve as filing openings for filing the different forms. When the sheets5, '7 and 9 are jogged up or superposed with the openings 15 inalignment as indicated in Fig. 7, the openings overlie an unbrokenportion of the back sheet 11.

The front sheet .13 is provided with tongues 17 so located as to permitthem to be bent down through the superposed openings 15. Preferablythese tongues are half -round as shown, their bases being equal to thediameters of the openings 15 while coinciding with the parallel verticaldiameters of the openings when the parts are assembled forms.

in jogged-up relation. The tongues, as best seen in Fig. 1, preferablyface in opposite directions for purposes which will appear. Referringnow to Fig. 2, it will be seen that the tongues 17 may be deflectedthrough the openings 15 in pages 5, 7 and 9 and secured to the backsheet 11. Herein (see Fig. 3) I have shown. the back sheet 11 asprovided with a stripe 19 of adhesive at the location of the holes bywhich the ends of the tongues are secured and which also directlysecures together the back sheet 11 and the immediately overlying page 9.

By the means described the various parts of the pad are firmly securedtogether and the pages 5, '7 and 9 hung on the deflected tongues whichjoin together the front sheet 13 and the backing sheet 11. The tonguesare easily bent and there is no drawing strain on the top or bottomsheet which might tend to pull any of the parts out of shape or causedisalignment of the printing This is particularly advantageous in casethe pads are manufactured by uniting long webs along one of their edgesand subsequently dividing them transversely to form the individual padsas shown in the figure as the drawing strain and so disalignment mightin such case be cumulative.

In the preferred form of the invention embodying a half-round tongue andround holes the tongue,

is easily passed through the round hole. The portion adjacent the basewhich passes through the 35 hole is of substantially the maximumdiameter. Thus if one of the pages 5, 7 and 9, referring to Fig. 2,should tend to shift to the left in that figure, then, referring to theright hand opening and the tongue therein, the tendency of this movement is to force a relatively short chord of the circular opening over aportion of the tongue of substantially full diameter and shiftingmovement is thus resisted. Since the two tongues face in oppositedirections, movement in either direction is prevented. The sections arefirmly joined with no opportunity for undesirable shifting and by simpleand inexpensive means not causing undue thickness at the joint.

I am aware that the invention may be embodied in other specific formswithout departing from the spirit or essential attributes thereof, and Itherefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive; reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.

I claim 1. A pad comprising a plurality of pages having openingstherethrough, a back sheet having portions underlying said openings anda top sheet having tongues deflected through said openings andadhesively secured to the face of such portions of the back sheet.

2. A pad comprising a plurality of pages having openings therethrough,which openings have a maximum dimension, a back sheet having portionsunderlying the openings, a top sheet having corresponding tongues cuttherefrom, the bases of which are of a width substantially equal to saidmaximum dimension of the corresponding opening and coincide with thesame, the tongues being deflected through said openings and adhesivelysecured to the face of such portions of the back sheet.

3. A pad comprising a plurality 01' pages having circular openingstherethrough, a back sheet having portions underlying the openings and atop sheet having tongues, the bases of which correspond in dimension andposition to parallel diameters of the openings and the bodies of whichextend in opposite directions, said tongues being deflected through theopenings and adhesively secured to the face of such portions of the backsheet.

4. A pad comprising a plurality of pages having circular openingstherethrough, a. back sheet having portions underlying the openings anda top sheet having half-round tongues, the bases of which correspond indimension and position to parallel diameters of the openings and thebodies of which extend in opposite directions, said tongues beingdeflected through the openings and adhesively secured to the face ofsuch portions of the back sheet.
